IMPROVEMENT IN BEDSTEAD-FASTENINGS.

Specification forming-part of'Letters Patent No. 142,973, datedSeptember 16, 1873; applic-ation filed 'June 20, 1873.

To all whom it may concern.:

Be it known that I, GALMAN WOLF, of the city of Rochester, in the countyof Monroe and State of New York, have invented a certain `new and usefulImprovement in Bedstead-y Fasteuings; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the saine.

My improvement belongs to that class in which a iianged Wedge is used,resting against the stop, and serving to draw out or tighten the hookupon the pin. As previously constructed, such Wedges are liable to drawaway or disengage from j the hook, owing-to the shape ortho form of thetongue-andgroovc connection between them.

My invention is intended to obviate this di'l'tlcnlty; and consists inthe peculiar form of the wedge and its anges, as hereinafter described,whereby this result is attained. It also consists in the combination,with the wedge and hook, of a spring for rctracting or throwing ont thehook when' the wedge is raised.

lfn the drawings, Figure lisa side elevationV of my improvement appliedto a bedstead; Fig. 2, a crosssection of -the same; Figs. 3 and 4,modilied forms.

.A represents the post, and B the rail, of a hedstead. C is the hook,which engages with the. cross-pin c in the ordinary manner to lock iherail and post together.. The shank of the hook extends through the stopor cleat G, and has a socket, t, through which -passes the wedge D, lywhich the tightening action is produced. The Wedge and socket are of peonlinr forni. The wedge is 'preferably pro vided with two right-anglediiangcs, c and d, prfgecting freni thc opposite faces, shown in' Figs. 3and fl, thatnpon the outside engaging.,r with a slot, f, ibrinedin 'thesocket et the hook, and that upon the inside running in. a slot, g,which is'cnt out ci the wood oi the rail. A blank, l1., is left atdhetop ni.' the ilange c, i'or the passage et' thc socket over or throughit in engaging' the pa The inner edge of the iianfge c, and also thsocket b, are made tiled, as shown :rt/i, so that when once ci ed thehooi; und. the vfcdge cannot be #Shielding-ui except by sliding' themapart, sov

that the sockethead passes over the Kblank h, This is an advantage, notonly in holding the parts together in store, but also in holding` thehook in line in the drawing action of the wedge, and thereby preventingbindin g, strain, and denting of the Wood. The iiange d is shorter thanthe length of the Wedge, leaving blanks 7c 7c at each end. Its length isintended to be such as to play up and down in the slot g of the railWithoutuneovering the slot at the .highest or lowest positiornso that nohugs can find an entrance.

It will be noticed that the inner edge of the v wedge is vertical, andmoves up and down against the stop Gr, the dange d and slot g, also,being vertical for the purpose. The opposite edge of the Wedge and itsliange c stands inclined, to produce thel necessary wedge action.

The advantages of this arrangement lie in the flanges c d ot' the Wedgestanding at right angles thereto, and arranged with the blanks or spaces7i L for the easy connection and truc working of the parts. An importantfeature consists in the dovetailed connection 0f the flange c and socketZ1, `and also in the short iiange (l, which forms a part of the squareside bearing againstthe stop.

To produce a retraction of the hook when vthe Wedge releases it, aspring, E, Fig. 1, may be employed, screwed or otherwise attached to theedge oi' the stop G, and resting at its lower end against a shoulder,in, of the shank of the hook. The tension of the wedge bends the springin\..'ard, as shown, and when relievcd the spring; throws thc hooleheadontward, so as toho easily. i'rce of the pin c..

I'Vhcn this spring is employed the wedge may be niade'with the singleflange d, as shown in- Y' Fig. 2, and the dovetail c' may beon the outerinstead of the inner edge.

v Having thus described my invention, I do not cla-ilu, hroz'idiy, aWedge for tightening the hook, ner do l claim a wedge havingr a flangeon thc "hack side and a groove in the face,

'with a `rib ol' thc hooleshanlc runnin@ in it;

but Y What I claim as new is- Y l. in combination with the hook U ol' abed-- stead fastening7 the wedge l), constructed with the Haugen 1 .Ilupon the opposite hueca,

2 ,l i y jv4 A Mginanud with tho blanks h k la fof conneoting the parts,said flange c boing dovetaled to fit the socket; of tho hook-shank, andsaid flange d playing in n vertical slot ofthe bedsjead-ral,

:is shown and described, and for thepurposo specified. i 2. Incombination with tho hook C and wedge l), the reacting spring E,engaging with shoulder, m, of the hook-shank, all constgructed,arranged, audpera'ting as slgown and des'cribed.

In witness whereof I have hereunto signet]t my name in the presence oftwo subscribing witnesses. i CALMAN WOLF.
